I’m currently writing a Java jenkins plugin and I’m facing a problem with stapler and Java-Javascript method bind.

My java file contains a method that I want to use in my jelly file when a button is clicked :

@JavaScriptMethod
public void method() {
  ...
}

var it = <st:bind value="${it}"/>

$('#Btn').click(function() {
    it.method();
});

This is simple and is supposed to work but the header in the request made by stapler used “Crumb” as for the CSRF token and jenkins is expecting “Jenkins-Crumb” so I get a 403.

This stackoverflow post was the problem same as mine but is quite old and I tried renaming it by editing the request and then got a 500 with “Crumb didn’t match” (/crumbIssuer/api/json give the same token as provided so no reasons).

I’m using Jenkins v2.452.1.
